I have seen a few dead Greenfinches during the last couple of years, near my feeders, but tonight I disturbed this poor Greenfinch while weeding. It almost certainly has trichomoniasis as it was displaying all the symptoms. Make sure all your feeders are keep clean, for more info go to

When younger I could have killed this bird saying it was a better and quicker end for it, thought about it tonight and could not do it.
old age cometh not alone !
